Popping up a menu with the menu trigger

Only button 3 can be used as a popup menu trigger. If defined, the menu trigger must display a pop-up menu.

For example, this menu script pops up the menu PopupClockMenu (which is used to start xclock with different startup options):

  1 rule='
  2 menu: PopupClockMenu
  3 {
  4   menu_item
  5   {
  6     title='digital'
  7     action
  8     {
  9 	begin
 10 	xclock -digital
 11 	finish
 12     }
 13   }
 14   menu_item
 15   {
 16     title='analog'
 17     action
 18     {
 19 	begin
 20 	xclock
 21 	finish
 22     }
 23   }
 24   dividing_line;
 25   menu_item
 26   {
 27     title='help'
 28     action
 29     {
 30 	help 'static_arg'
 31     }
 32   }
 33 remove_dynamic_rule PopupClockMenu
 34 dynamic_rule PopupClockMenu $rule
 35 popup PopupClockMenu $static_arg

lines 33-35
